By FullHD I mean 1920x1080 aka 1080p, including support for 1:1 pixel mapping (for computer usage).

Samsung plasma should be ok for 100.000 hours.

One really bad thing about 50" Samsung plasma is 18p processing / color only, which means 6bits per channel -> dithering is used to simmulate full color depth. And even stranger thing is that, despite dithering, all review sites say color is actually very good.
